GE Dishwasher Not Draining — Standing Water Fix

Common Symptoms

• Standing water at bottom of tub after cycle
• Dishes still wet and dirty at end of cycle
• Dishwasher hums but doesn't drain
• Water drains very slowly (partial drainage)
• Food particles floating in standing water

Most Likely Causes

1. 1

   Clogged Drain Filter Basket (Most Common — 80% of Cases)

   The drain filter basket sits at the bottom of the GE dishwasher tub, under the lower spray arm. It catches food particles, broken glass, and debris before they reach the drain pump. After months of use, the filter becomes clogged with food residue, grease, and soap scum. A clogged filter prevents water from draining. Remove the filter basket, rinse it under hot water, scrub with a brush, and reinstall — this resolves most GE dishwasher drain issues.

2. 2

   Kinked or Clogged Drain Hose

   The drain hose runs from the dishwasher drain pump to the sink drain or garbage disposal. If the hose is kinked (common after installation or if the dishwasher has been pushed back too far), water cannot drain. Also check for clogs inside the hose — food particles and grease can accumulate over time. Disconnect the hose at both ends and flush with hot water.

3. 3

   Garbage Disposal Knockout Plug Not Removed

   If a garbage disposal was recently installed and the dishwasher drain hose connects to it, the knockout plug inside the disposal inlet must be removed. The knockout plug is a small plastic disc that blocks the inlet port by default. If it wasn't removed during disposal installation, the dishwasher drain hose is blocked and water cannot drain. Check inside the disposal inlet — if you see the plug, punch it out with a screwdriver and retrieve it from inside the disposal.

4. 4

   Failed Drain Pump

   The drain pump is an electric motor-driven pump that forces water out of the tub and through the drain hose. If the pump motor has failed, you'll hear a humming sound during the drain cycle but no water movement. GE dishwasher drain pumps fail after 7-10 years or if a foreign object (broken glass, bone fragment) jams the impeller. Test by listening during the drain cycle — humming with no draining = bad pump.

Quick DIY Checks

1. 1Remove the lower dish rack. Twist the lower spray arm counterclockwise and lift it out. You'll now see the cylindrical drain filter basket in the center of the tub floor. Twist the filter basket counterclockwise (or lift straight up on some GE models) to remove it. Rinse the filter under hot running water and scrub with a brush to remove all food residue and grease. Reinstall the filter basket, spray arm, and dish rack.
2. 2Run a short rinse cycle and check if the dishwasher drains. If cleaning the filter resolved the issue, you're done. If standing water remains, proceed to the next step.
3. 3Pull the dishwasher away from the wall (disconnect power first). Locate the drain hose — it's a corrugated or smooth rubber/plastic hose (usually 5/8 inch diameter) that runs from the dishwasher to the sink drain or garbage disposal. Check for kinks or sharp bends in the hose. Straighten any kinks and secure the hose so it doesn't kink again when you push the dishwasher back.
